Matrix PRASAR UCS System Manual 73
PPPoE Service Name
• If your Internet Service Provider has provided a Service Name, enter the Service Name here. If your
Internet Service Provider has not provided a Service Name, do not configure this parameter.
Primary Server Address
• The system works as the Auto Configuration Server for the phone. Enter the LAN or WAN IP Address/
Domain Name of PRASAR UCS here. Default: blank. The phone sends the request for configuration files
to this Server Address.
If you have selected DHCP as Connection Type, the phone will get the Primary Server Address and Port
automatically from the DHCP Server. For this, use DHCP option 224 and Data Type as ‘String’ to provide
Server Address and Port from the DHCP Server.
For PPPoE and Static Connection Types, you need to enter the Server Address.
Primary Server Port
• Enter the SPARSH Port of PRASAR UCS here. The phone sends the request for configuration files to this
port.
Valid range of the port is: 80 or 1025–65535. Default: 80.
Secondary Server Address
• If required, you can also configure the Secondary Sever Address as a fallback option. If the registration
with the Primary Server fails the phone will send the registration and configuration requests to the
Secondary Server Address. Speech-cut or unclear speech may be observed during on-going mature calls.
Secondary Server Port
• Enter the Secondary Server Port. The phone sends the request for configuration files to this port if the
Primary Server fails.
Valid range of the port is: 80 or 1025–65535. Default: 80.
VLAN Setting
If your phone is connected to a virtual LAN, you need to configure VLAN Settings.
To enable the VLAN switch to correctly route packets generated by the phone and the computers (on the LAN) to
each other, the packets must be tagged with a VLAN header.
The VLAN header consists of the VLAN ID (12-bit) and Class of Service (CoS, 3-bit) for prioritization of traffic
11
.
The meaning of CoS bits with respect to traffic type is as follows:
11.The IEEE 802.1P standard allows Layer2 switches to prioritize the traffic, thus providing Quality of Service (QoS), that is, better han-
dling of data that pass over a network, thereby resulting in greater reliability and quality. Quality of Service (QoS) on Layer2 is referred
to as Class of Service (CoS) which is defined by IEEE 802.1P.
